In 2025, Martin Marietta Materials completed a corporate carbon footprint assessment and publicly disclosed its greenhouse gas (GHG) emissions according to the GHG Protocol, covering Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased energy) and Scope 3 (indirect emissions across the value chain).
However, Martin Marietta Materials has not published a category-level breakdown of its Scope 3 emissions, limiting visibility into specific value chain sources.

Compared to 2024, the total operational greenhouse gas (GHG) emissions of Martin Marietta Materials decreased by 4.24%, showing that the company has made progress in taking action to reduce the climate impact of its operations.ab
In 2025, the total Scope 1 emissions of Martin Marietta Materials were 2,800,000 metric tons of CO₂ equivalent (tCO₂e).a
Since 2020, Martin Marietta Materials's Scope 1 emissions have decreased by 37.85%, reflecting a declining long-term trend in Scope 1 emissions over time.ad
Compared to the previous year (2024), Martin Marietta Materials's Scope 1 emissions decreased by 3.45%, highlighting the company's efforts to lower direct emissions from assets it owns or controls.ab
In 2025, Martin Marietta Materials reported Scope 2 greenhouse gas (GHG) emissions of 458,319 tCO₂e without specifying the calculation method.a
Since 2020, Martin Marietta Materials's Scope 2 greenhouse gas (GHG) emissions (Unspecified Calculation Method) have decreased by 31.7%, reflecting a declining long-term trend in Scope 2 emissions over time.ad
Compared to the previous year (2024), Martin Marietta Materials's Scope 2 emissions (Unspecified Calculation Method) have remained relatively stable, indicating that Martin Marietta Materials's emissions have plateaued with no significant change in its energy consumption footprint.ab
In 2025, Martin Marietta Materials reported its Scope 2 emissions using an unspecified methodology.a
In 2025, Martin Marietta Materials reported 1,915,305 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2025 disclosure of Martin Marietta Materials includes a breakdown across 0 of the 15 Scope 3 categories defined by the GHG Protocol, matching the level of disclosure in 2024, demonstrating consistent Scope 3 emissions reporting coverage year over year.a
In 2025, Martin Marietta Materials reported total Scope 3 emissions of 1,915,305 metric tons of CO₂ equivalent (tCO₂e).a
In 2025, Martin Marietta Materials reported Scope 1 greenhouse gas (GHG) emissions of 2,800,000 tCO₂e and total revenues of USD 6,150 millions. This translates into an emissions intensity of 455.28 tCO₂e per millions USD.a
In 2025, Martin Marietta Materials reported a Scope 1 emissions intensity of 455.28 tCO₂e per millions USD. Compared to the peer group median of 2,471.18, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Martin Marietta Materials ranked 7 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Martin Marietta Materials is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Martin Marietta Materials reported a total carbon footprint of 5,173,624 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 52.04% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.ab
The largest contributor to Martin Marietta Materials's total carbon footprint was Scope 1 emissions, accounting for 54.12% of the company's total carbon footprint, followed by Scope 3 emissions at 37.02%.a
